“This feels to me a lot like how Rails felt back in 2005. A fundamental leap forward and an understanding of where web technology is going. I haven’t felt that way about Node.js or even its higher-level frameworks like Express or Batman. This feels like “The One”, even though I’ve been absorbing the docs and screencasts only for the last 20 minutes.” - highest rated comment from Hacker News
Using the Impress.js presentation framework requires front end coding knowledge, but you can make some really unique presentations with it (and they even included my ‘What The Heck Is Responsive Web Design?’ deck in there). Note: requires Chrome, Safari or Firefox 10.
